We live on the East Coast about 30 minutes from Charlottesville, Virginia and we're about to put both collard greens and Swiss Chard out for our spring garden. I was wondering what would be the earliest time for both.
It is almost certain you will not get frost after May 7 in your growing zone.
You can grow these crops in a cold frame and plant much sooner.
Here are some links with more information.

How do I stop bugs from eatting my collard greens
Pests include aphids, cabbage worms and the harlequin bug. Aphids are usually small, brown bugs that gather on the underside of the plant's leaves.
Cleaning the collards with a strong spray of water can help and you can also spray with a homemade soap spray.
These links have more information.

I’m in north Georgia and want to plant collards. When is the best time?
To get a fall harvest, you will want to plant about 8 weeks before the first frost. Now would be a good time to get a crop in before it gets too cool.

I'm going collard greens for the first time, and I have holes on the leaves... are they still safe to eat? how do I stop whatever is causing the holes?
They will be safe to eat, but I will need photos to confirm whether this was caused by insect or fungal infection. It can be difficult to stop the holes without knowing exactly what caused them. A photo can help me to see signs that will give me a better idea of what it going on.
In the meantime, this article will help you with their care: https://www.gardeningknowhow.com/edible/vegetables/greens/growing-collard-greens.htm
I lose my greens every year because of white butterfly worms. Is there anything that really works on stopping them?
I don't usually recommend specific products, but in this case I will, because I know it works. FoxFarm makes a product called Force of Nature Miticide. It is a very broad spectrum, very effective, organic treatment that comes in ready to use spray, or concentrate. Persistence is key, so keep spraying once per week or so, or after a rain, like we are getting today (I am also in TN).
How can I safely use epsom salts to help my garden plants (collards, tomatoes) grow?

I have 2 tree collards, currently in 5 gallon pots from nursery. I don't have a large garden. I wanted to plant in a 15-20 gallon terra cotta clay pot. I drove over 30 miles to purchase these tree collards (very hard to find in California), so i am very scared if i transplant them in a huge pot, they may die? What type of soil should i purchase? I hope i don't have to feed these tree collards with chemical fertilizers in order for them to grow well. Clearly, i don't know much about planting. Can you please help? Also, if you can recommend a great potting soil that is safe that would be awesome! Thank you greatly for your time and for this awesome site.
The container size will be just fine. What I would do is use a mix of potting soil and compost. This will supply the nutrients as well as provide the light soil for it to grow its best. This will cut the need to feed it, as you can just add more compost if it needs a boost later.
